This activity gets students to apply translational and rotational symmetry to create freeze-type patterns. The method suggested uses a printing block.
The patterns created by translation need to preserve the orientation of the figure. For example:
By contrast, the patterns created by rotation involve a change in orientation. For example:
Students may find that they can apply translation and rotation in combination. For example:
Another way of making patterns by reflection is to cut a tracing block from a square of card. Note that it is wise to mark the original corners of the square before cutting to help keep track of the original shape. For example:
The pattern can be duplicated across the whole page by repeated reflection.
